Whether you're celebrating a birthday or just another Wednesday, this is the perfect chocolate cake. The batter is made in one bowl and comes together in minutes. The chocolate flavor is STRONG thanks to the addition of coffee, which brings out the chocolate flavor. Vegetable oil and sour cream team up to make this cake extra moist. They also allow this cake to be egg free! After testing we found eggs made the cake too spongy and simply weren't needed here. The frosting is a whipped ganache for a less sweet frosting than a traditional chocolate buttercream. Be sure to give it time to cool before whipping or it won't whip properly.
